-The Solaris Porting Layer (SPL) is a Linux kernel module which provides
-many of the Solaris kernel APIs. This shim layer makes it possible to
-run Solaris kernel code in the Linux kernel with relatively minimal
-modification. This can be particularly useful when you want to track
-upstream Solaris development closely and do not want the overhead of
-maintaining a large patch which converts Solaris primitives to Linux
-primitives.

- $ ./configure
- $ make pkg
-
-If you are building directly from the git tree and not an officially
-released tarball you will need to generate the configure script.
-This can be done by executing the autogen.sh script after installing
-the GNU autotools for your distribution.
-
-To copy the kernel code inside your kernel source tree for builtin
-compilation:
-
- $ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
- $ ./copy-builtin /usr/src/linux-...
-
-The SPL comes with an automated test suite called SPLAT. The test suite
-is implemented in two parts. There is a kernel module which contains
-the tests and a user space utility which controls which tests are run.
-To run the full test suite:
-
- $ sudo insmod ./module/splat/splat.ko
- $ sudo ./cmd/splat --all
-
-Full documentation for building, configuring, testing, and using the
-SPL can be found at: <http://zfsonlinux.org>

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ (or the compiler's sysroot if not specified).
+ --with-spec=SPEC Spec files 'generic|redhat'
+ --with-config=CONFIG Config file 'kernel|user|all|srpm'
+ --with-linux=PATH Path to kernel source
+ --with-linux-obj=PATH Path to kernel build objects
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ *
+ * The race renders it unsafe to be used for serializing the freeing of an
+ * object in which the mutex is embedded, where the latter acquirer could go
+ * on to free the object while the former one is still doing mutex_unlock and
+ * causing memory corruption.
+ *
+ * However, there are many places in ZFS where the mutex is used for
+ * serializing object freeing, and the code is shared among other OSes without

+ * vmem_* is an interface to a low level arena-based memory allocator on
+ * Illumos that is used to allocate virtual address space. The kmem SLAB
+ * allocator allocates slabs from it. Then the generic allocation functions
+ * kmem_{alloc,zalloc,free}() are layered on top of SLAB allocators.
+ *
+ * On Linux, the primary means of doing allocations is via kmalloc(), which
+ * is similarly layered on top of something called the buddy allocator. The
+ * buddy allocator is not available to kernel modules, it uses physical
+ * memory addresses rather than virtual memory addresses and is prone to
+ * fragmentation.
+ *
+ * Linux sets aside a relatively small address space for in-kernel virtual
+ * memory from which allocations can be done using vmalloc(). It might seem
+ * like a good idea to use vmalloc() to implement something similar to
+ * Illumos' allocator. However, this has the following problems:
+ *
+ * 1. Page directory table allocations are hard coded to use GFP_KERNEL.
+ * Consequently, any KM_PUSHPAGE or KM_NOSLEEP allocations done using
+ * vmalloc() will not have proper semantics.
+ *
+ * 2. Address space exhaustion is a real issue on 32-bit platforms where
+ * only a few 100MB are available. The kernel will handle it by spinning
+ * when it runs out of address space.
+ *
+ * 3. All vmalloc() allocations and frees are protected by a single global
+ * lock which serializes all allocations.
+ *
+ * 4. Accessing /proc/meminfo and /proc/vmallocinfo will iterate the entire
+ * list. The former will sum the allocations while the latter will print
+ * them to user space in a way that user space can keep the lock held
+ * indefinitely. When the total number of mapped allocations is large
+ * (several 100,000) a large amount of time will be spent waiting on locks.
+ *
+ * 5. Linux has a wait_on_bit() locking primitive that assumes physical
+ * memory is used, it simply does not work on virtual memory. Certain
+ * Linux structures (e.g. the superblock) use them and might be embedded
+ * into a structure from Illumos. This makes using Linux virtual memory
+ * unsafe in certain situations.
+ *
+ * It follows that we cannot obtain identical semantics to those on Illumos.
+ * Consequently, we implement the kmem_{alloc,zalloc,free}() functions in
+ * such a way that they can be used as drop-in replacements for small vmem_*
+ * allocations (8MB in size or smaller) and map vmem_{alloc,zalloc,free}()
+ * to them.

-Subsystem debugging level mask.
+Cache expiration is part of default Illumos cache behavior. The idea is
+that objects in magazines which have not been recently accessed should be
+returned to the slabs periodically. This is known as cache aging and
+when enabled objects will be typically returned after 15 seconds.
+.sp
+On the other hand Linux slabs are designed to never move objects back to
+the slabs unless there is memory pressure. This is possible because under
+Linux the cache will be notified when memory is low and objects can be
+released.
+.sp
+By default only the Linux method is enabled. It has been shown to improve
+responsiveness on low memory systems and not negatively impact the performance
+of systems with more memory. This policy may be changed by setting the
+\fBspl_kmem_cache_expire\fR bit mask as follows, both policies may be enabled

+Depending on the size of a cache object it may be backed by kmalloc()'d
+or vmalloc()'d memory. This is because the size of the required allocation
+greatly impacts the best way to allocate the memory.
+.sp
+When objects are small and only a small number of memory pages need to be
+allocated, ideally just one, then kmalloc() is very efficient. However,
+when allocating multiple pages with kmalloc() it gets increasingly expensive
+because the pages must be physically contiguous.
+.sp
+For this reason we shift to vmalloc() for slabs of large objects which
+which removes the need for contiguous pages. We cannot use vmalloc() in
+all cases because there is significant locking overhead involved. This
+function takes a single global lock over the entire virtual address range
+which serializes all allocations. Using slightly different allocation
+functions for small and large objects allows us to handle a wide range of
+object sizes.
+.sh
+The \fBspl_kmem_cache_kmem_limit\fR value is used to determine this cutoff
+size. One quarter the PAGE_SIZE is used as the default value because
+\fBspl_kmem_cache_obj_per_slab\fR defaults to 16. This means that at

+The default warning threshold is set to eight pages but capped at 32K to

+enough to ensure the largest allocations are quickly noticed and fixed.
+But large enough to avoid logging any warnings when a allocation size is
+larger than optimal but not a serious concern. Since this value is tunable,

+ *
+ * 1) Constructors AND destructors. Recent versions of the Linux

+ * 2) Virtual address space backed slab. Callers of the Solaris slab
+ * expect it to work well for both small are very large allocations.
+ * Because of memory fragmentation the Linux slab which is backed
+ * by kmalloc'ed memory performs very badly when confronted with
+ * large numbers of large allocations. Basing the slab on the
+ * virtual address space removes the need for contiguous pages
+ * and greatly improve performance for large allocations.
+ *
+ * For these reasons, the SPL has its own slab implementation with
+ * the needed features. It is not as highly optimized as either the
+ * Solaris or Linux slabs, but it should get me most of what is
+ * needed until it can be optimized or obsoleted by another approach.
+ *
+ * One serious concern I do have about this method is the relatively
+ * small virtual address space on 32bit arches. This will seriously
+ * constrain the size of the slab caches and their performance.

- * Slab allocation interfaces
- *
- * While the Linux slab implementation was inspired by the Solaris
- * implementation I cannot use it to emulate the Solaris APIs. I
- * require two features which are not provided by the Linux slab.
- *
- * 1) Constructors AND destructors. Recent versions of the Linux
- * kernel have removed support for destructors. This is a deal
- * breaker for the SPL which contains particularly expensive
- * initializers for mutex's, condition variables, etc. We also
- * require a minimal level of cleanup for these data types unlike
- * many Linux data type which do need to be explicitly destroyed.
- *
- * 2) Virtual address space backed slab. Callers of the Solaris slab
- * expect it to work well for both small are very large allocations.
- * Because of memory fragmentation the Linux slab which is backed
- * by kmalloc'ed memory performs very badly when confronted with
- * large numbers of large allocations. Basing the slab on the
- * virtual address space removes the need for contiguous pages
- * and greatly improve performance for large allocations.
- *
- * For these reasons, the SPL has its own slab implementation with
- * the needed features. It is not as highly optimized as either the
- * Solaris or Linux slabs, but it should get me most of what is
- * needed until it can be optimized or obsoleted by another approach.
- *
- * One serious concern I do have about this method is the relatively
- * small virtual address space on 32bit arches. This will seriously
- * constrain the size of the slab caches and their performance.
- *
- * XXX: Improve the partial slab list by carefully maintaining a
- * strict ordering of fullest to emptiest slabs based on
- * the slab reference count. This guarantees the when freeing
- * slabs back to the system we need only linearly traverse the
- * last N slabs in the list to discover all the freeable slabs.
- *
- * XXX: NUMA awareness for optionally allocating memory close to a
- * particular core. This can be advantageous if you know the slab
- * object will be short lived and primarily accessed from one core.
- *
- * XXX: Slab coloring may also yield performance improvements and would
- * be desirable to implement.

- * overhead in __get_vm_area_node(). This function takes a single

- * adaptive mutexs were embraced and integrated with the scheduler. This
- * brought a significant performance improvement, but just as importantly
- * it added a lock owner to the generic mutex outside CONFIG_DEBUG_MUTEXES
- * builds. This is critical for correctly supporting the mutex_owner()
- * Solaris primitive. When the owner is available we use a pure Linux
- * mutex implementation. When the owner is not available we still use
- * Linux mutexs as a base but also reserve space for an owner field right
- * after the mutex structure.
- *
- * In the case when HAVE_MUTEX_OWNER is not defined your code may
- * still me able to leverage adaptive mutexs. As long as the task_curr()
- * symbol is exported this code will provide a poor mans adaptive mutex
- * implementation. However, this is not required and if the symbol is
- * unavailable we provide a standard mutex.

-Required missing symbols for FC11 kernels (2.6.29.4-167.fc11.x86_64)
-
-* get_vmalloc_info()
-There is no clean API in the kernel for modules to check the virtual
-memory state of the system. This information is available in user
-space under /proc/meminfo and the details for every virtual memory
-node are available under /proc/vmallocinfo.
-
-* groups_search()
-This support is easily replicated if the symbol is not provided by the
-kernel. However exporting the symbol from the kernel is preferable.
-This is required by the solaris credential API.
-
-* task_curr()
-This symbol is used by the solaris adaptive mutex implementation. If
-unavailable then all solaris mutexs behave strictly like linux style
-semaphones. If available then the mutex may spin for a short while,
-rather than sleep, if the holder of the lock is currently executing.
-
-* first_online_pgdat()
-* next_online_pgdat()
-* next_zone()
-Required helper functions for the zone iterators for_each_zone() and
-for_each_populated_zone(). These symbols were previously available
-in 2.6.17 kernels, marked unused in 2.6.18 kernels, and removed as
-of the 2.6.19 kernel series. The information is available in user
-space under /proc/zoneinfo.
